Abstract

The invention relates to an integrated HF circuit with attenuators, exhibiting an input, an output, and a number of field effect transistors as switching elements with a number of positive supply voltages, wherein the attenuators control, according to an attenuation state, which can be switched between two states, the amplitude of a reference signal, applied to the input, and produces an actual signal at the output. According to the invention, the attenuators exhibit a number of inductors and/or capacitors for phase compensation, and the field effect transistors may be driven without power.
